About EncryptWatch
EncryptWatch is a growing collection of free online tools for website owners, developers, and anyone who cares about security and privacy. We focus on utilities that help you encode data, generate strong credentials, verify file integrity, inspect tokens, and format structured data.
Privacy by design: tools marked “Runs in browser” process everything locally on your device using JavaScript — no passwords, keys, or files are uploaded to any server. For each tool we explain what it does, show an example, list its limitations, and suggest how to fix common problems.
A passed check is never a guarantee of security. These tools are provided for educational and diagnostic purposes.
